PCA8575DB,118

PCA8575 is a remote 16-bit I/O expander for I2C bus with interrupt. The PCA8575 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The PCA8575 has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs. Typical applications include LED signs and displays, servers, industrial control, medical equipment, PLCs and cellular telephones.
